MAYONNAISE-MIXER.

Specification of Letters Patent.

Patented June 22, 1915.

Application filed October 12, 1914. Serial No. 866,353.

To all whom it may concern:

Be it known that I, WILLIAM LANDSBERG, citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Mayonnaise-Mixers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention is a mixing machine, useful more especially for mixing mayonnaise or other dressings to which oil must be carefully added from time to time, and the object of the invention is to simplify a machine of this character and reduce the cost ,of its construction, While sacrificing none of its advantages. This object is carried out by constructing the machine as hereinafter more fully described andclaimed and as shown in the drawings wherein Figure 1 is a perspective view of this machine complete. Fig. 2 is an enlarged vertical section of the upper portion thereof, and Fig. 3 is a plan view of the latter. Figs. 4, 5 and 6 are sectional details which will be referred to hereinafter.

On a table 1 is mounted a square base 2 having a central cross bar 3 and an upright frame 4, the top bar 5 of the latter having bearings 6. Within said bearings are journaled a power shaft 7 and a driven shaft 8 connected by gears 9 and 10 in about the proportion of five to two, the power shaft having a fly-wheel 11 which may be driven by a belt although it is provided with a handle 12 so that it maybe driven by hand if desired. At the inner end of the driven shaft is a beveled gear 1.3 meshing with another beveled gear 14 which is rotatably mounted on an upright bearing 15 carried by the top bar 5. Through the hub of the beveled gear 14 and throughout the length of the bearing 15 extends the dasher shaft 16 which has a handle or eye 17 at its upper end by means of which it may be raised. Just beneath said handle it is provided with laterally projecting lugs or keys 18 adapted to be dropped into the notches 19 in the hub of the beveled gear 14 so as to connect these elements and cause said gear to rotate the dasher shaft 16, although by drawing up-v ward on the handle or eye 17 the shaft may be readily disconnected from the gear. The lower end of said shaft 16 carries a T-head 20 adapted to drop into a bayonet slot 21 formed in a boss 22 which is carried by the head 23 of the dasher 24. l/Vhile the latter may be of any suitable construction, I prefer that it have two wings as illustrated in the drawings, so that it will operate as set forth below. Directly beneath said boss the dasher carries at its bottom a depending pin 25 (see Fig. 6) which fits into a step bearmg 26 formed in the top of a casting 27, the latter having at its bottom a square socket 28 fitting removably over a square pin 29 which rises from the cross bar 3 of the base. Thus it will be seen that the casting 27 has a socket or step bearing 26 in its upper side in which the dasher rotates, and a socket 28 in its lower side to fit over the pin 29.

The body or tub 30 is by preference made of birch wood, is cylindrical and has an open top, and its bottom 31 has through it a hole 32 into which the casting 27 is fitted closely, being held in place by screws 33 or otherwise so as to prevent leakage. Near its'upper end the tub or body is provided with sockets 34 to receive the inner ends of spring bolts 35 as best seen in Fig. 5.

Mounted on the top bar 5 of the frame is a substantially triangular tank having a depth gage 41 on its front side, a hinged cover 42, and a. bottom 43 which slopes to an outlet 44 at its inner corner over the tub. This outlet is controlled by a valve 45 whose handle 46 is accessible from above. This tank may be fed by a pump 47 whose barrel 48 leads downward past one side of the frame and may be extended into a can 49 set under the table, as indicated in Fig. 1. By this means is supplied the oil which is mixed with the dressing as the latter is stirred by the dasher, but this oil should not be confused with the lubricating oil which is applied to the parts in any suitable way. In order to prevent the lubricating oil from getting into the dressing as the latter is mixed, a cup 50 may be secured to the dasher shaft 16 just above its T-head 20 and beneath the bearing 15, and yet this cup should be low enough to permit the shaft to be raised so that the T-head will disengage the bayonet slot 21.

The operation of this machine is as follows: Assuming that the tub is removed and washed, the proper ingredients for a given amount of dressing are placed therein, and the dasher inserted into the tub. At this time we will assume that the dressing fills the tub two-thirds or four-fifths full. It is now inserted into the frame 4: and pressed into place until the socket 28 drops over the pin 29 and the two spring bolts 85 drop into the sockets 34. At this time the boss 22 on the head of the dasher will stand beneath the cross bar 5 of the frame. The dasher shaft is now pushed downward by means of its handle 17 until its T-head 20 engages the bayonet slot :21 in said boss 22, at which time its key 18 will engage the notches 19 in the gear 14:, and by this means the dasher is centered' within the tub and its shaft is connected to the driving mechanism, The latter is then moved by rotating the fiy-wheel, either by machinery of the diasher within the tub causes the blades of the former to mix the dressing very thoroughly. Meanwhile the handle 16 is manipulated tojopen the valve to the proper degree, and oil from the tank 450 is fed to the dressing during the process of stirring, the tank being replenished from time to time by manipulating the pump 47 so as to draw this oil from the can 19. When it is desired to remove the charge with which the tub has been filled, the process reversed so as to first disconnect the dasher shaft 16 and raise it through the bearing 15 and gear wheel 142, after which the spring bolts 35 can be retracted, and" the tub and its contents bodily removed from the frame. Ihe dasher is then lifted out of the dressing, when its pin 25 comes out of the step bearing26 in which it had formerly rotated.

I do not wish to be limited to the materials or proportions of parts, and specific details are not essential to the successful operation of this invention.

Ordinarily the driving'mechanism will be rotated to the right to turn the dasher in the proper direction for stirring the dressing,

i and when it is' desired to remove the daslier it is only necessary to stop the driving'mechanism and give it a short turn in reversed direction so that the T-head 20 will be disco ies or this patent may be obtained for or by hand, and the rotation engaged from the bayonet slot 21. I would havethe dasher shaft 16 fit the tubular bore of the hub in the gear wheel 14 with some friction so that when 'drawn upward by its handle 17 it will remain elevated with its T-head above the upper line of the tub,- thus permitting the latter to be withdrawn and replaced.

WVhat I claim is:

1. In a mixing machine, the combination with an upright frame mounted on a support, a tub in said frame, a dasher within said tub, and a boss rising from the head of the dasher above its bearing and having a bayonet slot; of bearings rising from the top bar of said frame, adriving mechanism journaled in said bearings and having a gear, a second gear driven thereby and hav ing a tubular hubwith radial" notches" in its upper end, a shaft slidably mounted through said hub and having keys adapted to engage its'notches, a head at the lower end of said shaft adapted to engage said bayonet slot,

and a hande at the upper end of the shaft;

2. In a mixing' machine, the combination wlth a framework lncl-u'di'ng' a cross-bar, a

wheel journaled and having a tubular hub with; radial notches in the upper end of the hub, mechanism for rotating said wheel, a body beneath said'bar, a d'asher therein having a head at its upper end, and a boss rising from said head and having a transverse slot of a vertical dasher shaft slidably mounted through the hub of said wheel and having keys near its upper end and: a head at itslower end adapted to engage said slot when the keys engage the notches, and an oil cup on the framework surrounding the shaft above its head.

In testimony whereofI affix my signature in presence of two witnesses;

WILLIAM LANDSBERG.
